摘要

本次设计为110/10kV广阳变电站电气主接线的初步设计，并绘制电气主接线图。该变电站设有两台主变压器，站内主接线分为110kV、10kV两个个电压等级。110KV电压等级采用双母线接线，10KV电压等级采用单母线分段接线。根据中央信号系统的基本知识以及常规中央音响信号系统的工作原理及典型接线分析和带自动重合闸装置的断路器控制回路。论文主要内容如下:

变电所中央信号是为了方便运行人员及时发现与分析故障，迅速消除和处理事故，统一调度和协调生产。在变电所中除了依靠测量仪表来监视设备运行情况外，还必须借助灯光和音响信号装置来反映设备正常和非正常的运行状况，可以更直观、更醒目、更能引起人们的注意，同时由于各种信号代表不同的提示信息，为运行人员提供了设备异常或事故的对象和性质，帮助运行人员做出正确的判断。

①介绍了中央信号各回路的分类以及对各回路的基本要求；并且详细介绍了事故信号和预告信号装置的功能。

②事故信号和预告信号作为中央信号中的重中之重，在设计中主要选用了性能比较稳定的ZC-23型的冲击继电器，并对各回路的工作原理及作用进行了详细的介绍。其中还对预告信号的瞬时预告信号和延时预告信号两部分分别作了介绍。

③对自动重合闸装置的要求进行了分析，其中主要对带三相一次自动重合闸的断路器控制回路进行了详细分析。

Abstract

The substation central signal is for the sake of convenience circulate personnel in time detection and analysis break down, quick cancellation and processing trouble, unify to adjust a degree to harmoniously adjust the substation in addition to depend on diagraph appearance to surveillance equipments circulate circumstance, return have to ask for help of light and stereo set signal equip to reflection the equipments be normal and not normal of circulate condition, can keep a view more, more refreshing, more ability cause people of attention, in the meantime because of various signal representative dissimilarity of hint information.

The thesis main contents is as follows:

⑴Introduction central each back track of signal of classification and to each back track of basic request;And detailed introduction

The function settle a dispute past signal and prior announcement signal equip.

⑵Trouble signal and prior announcement signal are in the central signal of heavy medium of heavy, in the design main chose to use

Function more stability of the pound at of type ZC-23 is after the electric appliances, and to the work of each back track principle and function carry on detailed of among them to prior announcement signal of moment prior announcement signal with postpone prior announcement signal two part made introduction respectively.

⑶ To auto heavy match Zha to equip of request carried on analysis, among them main to take three mutually an auto heavy matched the chopper of Zha control back track to carry on detailed analysis.

Key words: Ralay protection, Central signal, Trouble signal, Prior announcement signal
